$\text{ In comparison to a }0.01\mathrm{M}\text{ solution of glucose the depression freezing point of a }0.01\mathrm{M}{\mathrm{MgCl}}_2\text{ solution is ........}$

$\text{ As we know depression in freezing point is directly related to van't Hoff factor }\left(\mathrm{i}\right)\text{ according to which greater the value of }\mathrm{i}\text{ greater will be the depression in}$
$\mathrm{freezing} \mathrm{point}.$

 

$\text{ Hence, depression in freezing point of glucose is about }3\text{ times of glucose. }$
